The Allen-Bradley 1485-R T1H4 (cat 1485-A TIH4) is a versatile and robust ControlLogix Micro I/O module from Rockwell Automation's Allen-Bradley product line. This micro I/O module is designed to provide high-performance input and output capabilities for distributed control systems, occupying minimum space in control panels.
The 1485-R T1H4 is compatible with ControlLogix 1756-L33 and ControlLogix 1756-L34 input/output power supplies. This module can support up to 22 discrete I/O points (16 inputs and 6 outputs). The inputs can be configured for various functions, including normally open (NO), normally closed (NC), and combination (NC/NO) inputs. The module also provides two isolated DC outputs, with one output rated for up to 250mA and the other for up to 1A.
The Allen-Bradley 1485-R T1H4 is engineered to deliver fast response times, ensuring reliable performance even during demanding applications. This module features four high-speed digital inputs (HSDI) and eight high-speed digital outputs (HSDO), which can operate at up to 25kHz update rates. Additionally, the module includes eight volt-free contact (VFC) input and four volt-free contact output terminals that can be configured for various applications, including floating and normally closed contacts.
This micro I/O module is constructed with high-quality materials for improved durability and long-lasting performance. Features, such as EMC/RFI filters, help protect against electromagnetic and radio-frequency interference for optimal system operation. The unit is also designed to withstand harsh environments, as it is rated for a temperature range of -20 C to 60 C (0 F to 140 F).
Installing the Allen-Bradley 1485-R T1H4 is a breeze, thanks to its flexible mounting options and configurable I/O points. The module can be installed on a DIN-rail or a backplane. Integrating this micro I/O module into your system is simple with Rockwell Software through RSLogix 5000 or FactoryTalk DesignSuite applications, enabling efficient engineering, implementation, and optimization of your control system.
Overall, the Allen-Bradley 1485-R T1H4 (cat 1485-A TIH4) is a valuable asset for any industrial automation project, providing a compact and competent solution for handling dispersed input and output requirements with high speed and precision.
The Allen-Bradley 1485-R-T1H4 and the Cat 1485-A-TIH4 are both compact input/output (I/O) modules from Rockwell Automation's Allen-Bradley line and are functionally equivalent. They are drop-in replacements for each other, meaning they have the same form factor, I/O points, and communication capabilities. Here are some pros and cons of each:
Allen-Bradley 1485-R-T1H4: Pros:1. Wide range of input types: Support for analog inputs, discrete inputs, and high-speed discrete I/O.
2. Easily Configurable: Compatible with Rockwell's RSLogix 5000 and Logix5000 PLC programming software.
3. Flexible communication: EtherNet/IP, ControlNet, and DeviceNet protocol support.
4. Dust-tight and water-resistant: ratings of IP66/67, making it ideal for industrial environments.
5. Wide operating temperature range: from -40 to 140 F (-40 to 60 C).
6. Easy installation: Drop-in replacement design.
Cons:1. May be considered older technology.
2. Higher power consumption compared to newer models.
3. Limited memory: Offers less data logging capability and fewer user-defined data words than newer models like the 1756-ICM or 1767-ICM.
Cat 1485-A-TIH4: Pros:1. Wide range of input types: Support for analog inputs, discrete inputs, and high-speed discrete I/O.
2. Easily Configurable: Compatible with Rockwell's RSLogix 5000 and Logix5000 PLC programming software.
3. Flexible communication: EtherNet/IP, ControlNet, and DeviceNet protocol support.
4. Dust-tight and water-resistant: ratings of IP66/67, making it ideal for industrial environments.
5. Wide operating temperature range: from -40 to 140 F (-40 to 60 C).
Cons:1. May be considered older technology, similar to the Allen-Bradley 1485-R.
2. More expensive than newer models, like the 1756-ICM or 1767-ICM.
3. Limited memory: Offers less data logging capability and fewer user-defined data words than newer models.
Conclusion:Both the Allen-Bradley 1485-R-T1H4 and Cat 1485-A-TIH4 are functional equivalents suitable for industrial applications requiring input/output capabilities. They provide a wide range of input types, configurability, flexible communication options, and rugged design. However, they are considered older technology and offer less data logging and memory compared to newer models. With their compatibility with commonly used Rockwell software and their robust features, these modules can handle most industrial applications effectively. However, the decision between these two may come down to cost, as the Cat 1485-A-TIH4 tends to be more expensive than the Allen-Bradley variant. Ultimately, whether you choose the Allen-Bradley 1485-R-T1H4 or the Cat 1485-A-TIH4 depends on your specific application requirements, budget, and personal preference.
Recommendation:Based on the pros and cons, if your application demands industrial-quality input/output modules with a decent memory capacity, consider newer models like the 1756-ICM or 1767-ICM. However, if you're on a tighter budget or working within specific restrictions and require the flexibility and ease-of-use of these older models, the Allen-Bradley 1485-R-T1H4 and Cat 1485-A-TIH4 can still do the job efficiently.
